Turn your old computer into a PlayStation-like gaming machine with Lakka
Lakka is a free and open source Linux distribution that turns a small computer into a full-fledged gaming console. It has an attractive and easy-to-use interface with eye-catching colors and a user experience similar to that of the PS4.
You can install it on your SD card or USB flash drive and set it up and play it directly. It has a wide range of joypad support along with the ability to use your PlayStation, XBox and Nintendo controllers.
If you don't have an old computer or its capabilities are weak to use Lakka distribution, you can customize it for devices that cost low and reach $ 30, as it supports a variety of computers, such as Raspberry Pi, Raspberry 2, HummingBoard, Banana Po, Odroid, CuBox-i, Cubietruck, and Cubieboard 2.
